CARTON-SEALING MAOHDKE.

and useful Improvements in Carton-Sealing Machines; and I do hereby declare the following to be a full, clear, and exact descrip tion of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to carton sealing machines and has for an object to provide a device of the class with improved features of economy of construction and operation.

A further object of the invention is .to

provide an improved carton sealing. ma-

chine adapted to seal both ends of a carton simultaneously and retain such sealed carton in closed position untilthe sealing cement has had opportunity to adhere.

With these and other objects in view the invention comprises certain novel constructions, combinations and arrangement of parts as will be hereinafter more. fully described and claimed.

In the'drawings: Figure 1 is a view of the improved carton sealing machine in side elevation. Fig. 2 is a view ofthe sealingmachine in top plan. Fig. 3 is a sectional view longitudinally through the machine as indicated on line 33 of Fig.2. Fig. 4 is-a view of the carton sealing machine in end elevation as indicated by arrow 4 of Figs. 1, 2 and 3. Fi 5 is a perspective view of one of the flap c osing wings. Fig. 6 is 'a perspective view of the guide for holding one of the flaps in engagement with the pasting roller. F ig. 7 is a perspective view of one of the cartons.

Like characters of reference designate corresponding parts throughout the several views.

The improved carton sealing machine which forms the subject matter of this application comprises a bed 10 of any desired or predetermined length, the length being determined by the conditions under which the device operates, upon which are mounted paste rollers 11 carried upon a shaft 12 and driven in any approved manner as by the belt 13 acting upon'the pulley 14 and receiving power from any source as the pulley 15 carried upon the shaft 16. The paste Specification of Letters Patent.

rollers 11 rotate in a paste well 17 so that the under side of such rollers are continually immersed in paste.

At one side of the paste rollers blocks 18 are erected having springs 19 secured thereto, the said blocks [being undercut as indicated Patented May 9,1916.

Application filed April 24, 1914. Serial No. 834,253.

more particularly at 20 in Fig. 4.. Extending across between the blocks 18 is a bridge brace 21 uponwhich are mounted springs 22 which bearupon the top of the carton and hold it toposition 'while it is being moved through the machine. Mounted also upon this bridge brace 21 are guides 23 having their extremities extending under guides 24 which partially cover the paste rollers 11. The guides 24 are supported upon brackets 25, the combination of the guides and the brackets being shown in perspective at Fig. 6. Between the blocks 18 and the paste rollers 11 wings 26 are erected which serve to guide the cartons in their passage through the machine.

At the side of the paste rollers opposite the blocks 18 springs 27 areperccted which serve to hold the several flaps of the carton in the position in which'they arrive from the paste rollers until seized manually by the operator positioned at that point. Far I ther along on the bed 10 rollers 28 are journaled upon vertical shafts with belts 29 running over such rollers and over other rollers 30 which latter rollers are carried upon a cross bar 31 adjustable by means of screws 32 relative to the bars 33, which extend between the rollers 28 and 30. It will be apparentthat the belt 29 passing about these two rollers may be tightened by the manipulation of the rollers 30 until they assume any desired degree of tautness. The bars 33 are provided intermediate their ends with slots 34: and shafts 35 extending through said slots and connected by means of springs 36. The shafts 35 carry rollers 37 which bear against the inner section of the belts 29 and by reason of the resiliency of the springs 36 tend to hold such belt sections yieldingly toward each other. Adjacent the rollers 30 a bridge bar 38 is erected with springs 39 carried thereby which tend to position and guide the cartons between the belts 29. The belts are driven in any approved manner, here shown conventionally as having the rollers 28 provided with shafts 10 which extend downwardly under the bed 10 and carry pulleys 41 which are connected by means of'belts 42 with pulleys 43 carried upon the shaft 16. It will be obvious, therefore, that when the shaft 16 is driven, through the medium of the belts 13 and 42 the paste rollers 11 will be rotated and the belts 29 driven.

The carton which is employed withthis machine is shown at Fig. and comprises a body portion 44 which is filled with the desired material. The ends of'the carton are provided with flaps 45, 46, 47 and 48. In operation the operator seizes the carton in the hands and closes the flaps 46 into position as desired, inserting the carton in the machine, the flaps 47 engaging against the springs 19 with the flaps 48 passing under the undercut 20 and the flaps 45 passing under the bridge 21 and under the springs 23. The carton is moved forward until the springs 19 engage the flaps 46 when it is released by the operator and another carton put into the machine in the same manner. The insertion of the second carton moves the first carton along until the flaps 48 are engaged between the wings 26 when they are turned upwardly to cover the flaps 46 and 47. Simultaneously the flaps 45 are bent downwardly under the guide 24 and pass between the guide 24 and the paste roller 11. The rotation of the paste roller serves to move the carton forwardly through the machine into engagement with the springs 27 which hold all of said flaps 46,

47 and 48 in closed position with the paste flaps 45 still remaining open. The operator at this point manually closes the flaps 45 down upon the fiaps'48 and moves the carton along between the springs 39 and intotween each block and an adjacent roller,

said wing being curved longitudinally and curved transversely from a substantially horizontal position in a plane with the lower side of the carton to a vertical position, the concave portion of the wing being positioned to engage one flap of the carton on the edge opposite its attached edge, and means for engaging the oppositely located flap of said carton.

2. In a carton sealing machine, a plurality of paste rollers spaced apart, a plurality of guide blocks, a concave wing member located between each block and an adjacent roller,

a guide for each roller having a deflected end portion, a bridge member connecting the blocks, a guide extending from the bridge member. to each roller, projecting under the deflected portion, and located opposite the concave portion of the adjacent wing, said wing member being curved longitudinally and having its concave portion positioned to engage the flap of a carton.

In testimony whereof I alfix my signature in presence of two witnesses.
